38#
39# DESCRIPTION:
40#	If a storage pool has activated hot spares,
41#	create snapshot and detach the basic vdev,
42#	the hot spare should become the functional device, and
43#	the data in snapshot should keep integrity.
44#
45# STRATEGY:
46#	1. Create a storage pool with hot spares activated.
47#	2. Create some files, create a snapshot upon filesystem
48#	3. Activate a spare device to the pool
49#	4. Create some files, create an new snapshot upon filesystem
50#	5. Do 'zpool detach' with the original device
51#	6. Verify the 2 snapshots are all kept, and verify the data integrity within them.
52#
53# TESTABILITY: explicit
54#
55# TEST_AUTOMATION_LEVEL: automated
56#
57# CODING STATUS: COMPLETED (2006-06-07)
